Happy New Year to all, Hubby and I are checking out earth boxes for planting ornamental chile peppers (Thai Dragons, Serranos, Jamaicans, Super Chiles) this coming growing season. We noticed in the Earth Box information that 8 plants can be planted per box (the boxes are 30 inches long). I thought pepper plants needed at least 12 inches of room. For those of you who have tried the earth box, how many plants do you recommend we plant per box? Thanks in advance for your help-Debbie & Marty (lost in middle America)
